I have been looking around for a while to solve this issue but maybe I am not using the right keywords or something.
I plan to use the Dabby DVB,DAB+, FM USB tuner. I plan to plug this into factory antenna, which is an amplified antenna. I have all the necessary plugs/cables to convert from OEM to RF.
The question is, can I just hook the antenna power cable to 12v DC or do I need to hook it up to 5v or something?
